• sublisation, as evidenced by the build-up of alkali deposits along <br /> the banks of ephemeral streams. Thus, surface runoff occurs <br />predominantly in response to anowmelt and very heavy rainstorms. <br />The quantity and quality of surface eater reflect limited eater <br />supply and availability in the general area. <br />The proposed permit area is drained by Foidel, Middle and Fish <br />Creeks, as show on Map 4, Energy Mine No. 3 Hydrology. All <br />streams, lakes, ponds, springs and discharge locations, both <br />ezisting and planned, are identified on the map. Areas of mining <br />disturbance are within the watershed of Middle Creek. Effects of <br />surface mining operations at Energy Mine No. 3 were considered <br />coincidental to the surface eater hydrology of the area during <br />• mining. Eecords for four years from DSGS gaging stations indicate <br />that Foidel and Middle Creek are intermittent streams, with no base <br />flow aad no year-round contribution from ground water discharge. <br />Three years of data from a gaging station operated by the U.S.D.A. <br />Science and Education Administration ("SEA") shows that Fish Creek <br />is a perennial stream which receives about 25 percent of its total <br />flow from ground water discharge (Boettcher, 1972). However, as <br />evidenced by records from 1955-1973 obtained at a DSGS gaging <br />station on Fish Creek as it enters Twentymile Park, most of Che flow <br />is from anowmelt at the headwater area in the Dunkley Flat Tope ten <br />miles upstream. Foidel, Middle and Fish Creeks all drain into <br />perennial Trout Creek . <br /> <br />2.04-47 <br />
